Risk Factors for Urinary Tract Infection After Renal Transplantation and its Impact on Graft Function in Children and Young Adults.
Summary of "Risk Factors for Urinary Tract Infection After Renal Transplantation and its Impact on Graft Function in Children and Young Adults."
PURPOSE:
Urinary tract infection will develop in 40% of children who undergo renal transplantation. Post-transplant urinary tract infection is associated with earlier graft loss in adults. However, the impact on graft function in the pediatric population is less well-known. Additionally the risk factors for post-transplant urinary tract infection in children have not been well elucidated. The purpose of this study was to assess the relationship between pre-transplant and post-transplant urinary tract infections on graft outcome, and the risk factors for post-transplant urinary tract infection. MATERIALS AND
METHODS:
A total of 87 patients underwent renal transplantation between July 2001 and July 2006. Patient demographics, cause of renal failure, graft outcome, and presence of pre-transplant and post-transplant urinary tract infections were recorded. Graft outcome was based on last creatinine and nephrological assessment.
RESULTS:
Median followup was 3.12 years. Of the patients 15% had pre-transplant and 32% had post-transplant urinary tract infections. Good graft function was seen in 60% of the patients and 21% had failed function. Graft function did not correlate with a history of pre-transplant or post-transplant urinary tract infection (p >0.2). Of transplanted patients with urological causes of renal failure 57% had post-transplant urinary tract infection, compared to only 20% of those with a medical etiology of renal failure (p <0.001).
CONCLUSIONS:
In this study there was no correlation between a history of urinary tract infection (either before or after transplant) and decreased graft function. History of pre-transplant urinary tract infection was suggestive of urinary tract infection after transplant. Patients with urological causes of renal failure may be at increased risk for post-transplant urinary tract infection.

Medical and Biotech [MESH] Definitions
Intestinal Fistula
An abnormal anatomical passage between the INTESTINE, and another segment of the intestine or other organs. External intestinal fistula is connected to the SKIN (enterocutaneous fistula). Internal intestinal fistula can be connected to a number of organs, such as STOMACH (gastrocolic fistula), the BILIARY TRACT (cholecystoduodenal fistula), or the URINARY BLADDER of the URINARY TRACT (colovesical fistula). Risk factors include inflammatory processes, cancer, radiation treatment, and surgical misadventures (MEDICAL ERRORS).
Uropathogenic Escherichia Coli
Strains of Escherichia coli that preferentially grow and persist within the urinary tract. They exhibit certain virulence factors and strategies that cause urinary tract infections.
Bacteriuria
The presence of bacteria in the urine which is normally bacteria-free. These bacteria are from the URINARY TRACT and are not contaminants of the surrounding tissues. Bacteriuria can be symptomatic or asymptomatic. Significant bacteriuria is an indicator of urinary tract infection.
Urology
A surgical specialty concerned with the study, diagnosis, and treatment of diseases of the urinary tract in both sexes, and the genital tract in the male. Common urological problems include urinary obstruction, URINARY INCONTINENCE, infections, and UROGENITAL NEOPLASMS.
Schistosomiasis Haematobia
A human disease caused by the infection of parasitic worms SCHISTOSOMA HAEMATOBIUM. It is endemic in AFRICA and parts of the MIDDLE EAST. Tissue damages most often occur in the URINARY TRACT, specifically the URINARY BLADDER.
